Delayed Response for a Fault - Business

My telephone and ADSL line went down on Monday last week. This is my business line, so I reported the fault immediately. I was told that a technician would attend to the fault within 24 - 48 hours. I did not hear anything from Telkom last week. I phoned back twice and was told that my fault would be escalated and marked as urgent. Up until now I have still not had a technician contact me and I have had no correspondence from Telkom. We have been without phone lines or internet for 7 days now!! I am shocked at this disgusting service!!
